Stress test cpu ram

At WePC, we are committed to ensuring that all your GPU questions are answered. Sometimes we focus on big questions, such as "What is the best graphics card in 2019?"...At other times, such as today, we focus on stress testing.

Today, we will explain what they are, why they are needed, which ones to use, and how to run them on their own. Before the end of this article, we hope that all your urgent questions will be answered, but if you have any questions, we invite you to comment below. The

GPU stress test is an application that pushes the GPU to its absolute limit. This means making full use of its processing power, using all the power available to the card, while increasing cooling and temperature as much as possible.

In most cases, real applications (such as games or even high-end games) will not be used as stress tests, because even if they exceed the limits of your GPU, they will not do so to the point where you risk system failure or overheating. On the other hand, the

stress test was built to cause crashes or overheating. Or, more precisely, to ensure that the component in question does not do so during normal or heavy use. That's why it's a test and the only way to pass is to let the component in question (the GPU in this case) continue to run smoothly.

These tests are especially helpful for those who are trying to find stable overclocking (which is why you sometimes hear it called graphics card stability testing) or various troubleshooting issues that can be encountered while upgrading components, etc.

That said, the GPU isn't the only component that's been stress-tested. Other common candidates for the stress test include CPU and RAM. If you want to stress test your CPU, we recommend using apps like Prime95 or Aida64. At the same time, it is better to use Memtest86 to test the RAM, which is very suitable for diagnosing RAM problems.

If you are interested in using these applications for stress testing, please let us know and we may do some special tutorials for them. However, for the scope of this article, we will focus on GPU stress testing and teach you all about how to do it.

Ideally, you should use the overclocking application of your choice to monitor your temperature when stress testing. If you are unfamiliar with GPU overclocking and don't know what to use, just go to our GPU overclocking tutorial or install MSI Afterburner to monitor. In Afterburner, you should see the correct window, which will provide active reads for your GPU. The

embedded above is an image from my own Afterburner window and my GPU is idle. You generally only need to worry about two readings here: GPU temperature and GPU utilization. During the stress test, you should expect the temperature to reach 90 °C (194 °F) and the GPU usage to increase to 100%. Don't be surprised or worried by any of these numbers.

However, if your GPU exceeds 90°C, especially if it exceeds 100°C or higher, be careful. Your GPU may overheat beyond its limit, and doing so for a long time may damage your GPU. If you find that the temperature is too high, it is best to increase the fan speed or lower the GPU clock. A particularly aging GPU may require active sub-frequency to prevent overheating and maintain stability, but this is usually the worst case.

After installing the monitoring/overclocking software, it's time to talk about stress testing.

Today, I will introduce you to the top three GPU stress tests. Whether you need to stress test Nvidia GPU or AMD GPU, you can use only one of them, all of them, or any combination of them. However, if you choose to use only one, we recommend FurMark.

is suitable for: overclocking and general stability test

FurMark is a free OpenGL stress/benchmark test, in the past five years, it occupies the supreme position in the field of enthusiasts. Thanks to continuous updates to the latest GPU, easy-to-use interface, and unparalleled ability to eliminate jitter and push the GPU to the limit, FurMark has remained relevant since its launch.

If you only plan to run one of the stress tests, we recommend that you use FurMark. It has been the first choice of the enthusiast community for a long time, and it is completely free. However, we only recommend using it for our basic or high stability tests. If you plan to run longer and more extensive performance and stability tests, use one of Unigine's demos.

is best for: testing stability and real-world performance.

If you want to run free GPU stress tests for more realistic scenarios (and look more beautiful), Unigine Heaven is a good starting point. Although it has celebrated its 9th birthday, this benchmark is still the most popular, as a standard for comparing current GPUs to previous generation GPUs, as a tool for checking stability, and as an interesting little benchmark tool.

Although most of the Unigine Heaven features are completely free, if you want to use features like automatic benchmark loops, you need to spend some money, which is useful for expanding your stress testing scenarios.

If you want something denser (and built from the ground up for cutting edge GPUs), you can try Unigine's other stress test software: Overlay.

is suitable for: modern GPU and VR

Unigine overlay may not be as (aesthetically) beautiful as Unigine Heaven, but from a technical point of view, it is much more demanding. Superimposed and tested various advanced lighting and shadow functions; in fact, it was designed to yield models such as the GTX 1080 Ti.

Both are locked behind a $20 paywall (not bad if you have already spent hundreds of dollars on VR setup). You can still use the free version for stress testing, but you need to keep it for a shorter stress test, or come back from time to time to rerun the benchmark.

Once you decide which of these three you want to use and install them, continue to the next section.


Now that you know what a stress test is and which stress test to use, it's time to show you how to run a graphics card test.

Note: Although we do not want your system to be damaged during these tests, it is possible. Therefore, we are not responsible for any damage you may cause to the system while using these tests.


First, continue setting the overclock of your choice. If you are not overclocking, but simply testing the performance or stability of the GPU, skip this step.

If you want to overclock but haven't started yet, check out our GPU overclocking guide to get started. If you continue from here, we'll assume you're testing overclocking or system stability under standard clock.


Close everything. If you need to use your PC during a stress test and don't have time to ditch it, a lightweight browser like Opera may be fine, but steer clear of tasks that increase GPU usage, like watching YouTube videos. or Netflix.

You should avoid any kind of visual media consumption when performing stress tests or any kind of benchmark testing, because you risk getting confusing results or crashing the system in extreme cases.

At this point, all that should open on the desktop is the overclocking / monitoring software.


Now, open your stress test application and click Run. You might want to mess up different settings like resolution, full screen, graphics presets, etc. You can do this if you want, but it is not necessary to run this type of test.

Regardless of which option you choose, your GPU should reach 100% utilization and its temperature should be as high as possible. In short, it is really a matter of personal preference.

To use the Unigine application, we recommend running it in full screen at its original resolution ... If it's just that, you have some beautiful things to watch while the GPU is running. However, make sure your temperature and usage readings are still accessible.


Now is the time to decide when to run the video card test. We will first introduce the three basic ranges and why you can choose them over the other options.

Note: FurMark is only recommended for basic testing. Running it for more than an hour can eventually damage your GPU, so we recommend using Unigine stress tests that exceed the basic stability layer.

This is a basic test. If your GPU has unstable overclocking or basic cooling issues after running for 30 minutes, FurMark, Heaven, and Superposition should all fail. If it happens here, your system must be licensed for any kind of general use or media consumption, and an average-sized gaming session (12 hours or less) is also a safe bet. If your system fails this test, lower the clock, turn on the fan, and try again.

If you want to ensure the stability of a long gaming session (35 hours), a one-hour stress test should reveal whether your system can actually handle such a gaming session. If it passes the Great Stability test with no glitches or serious overheating issues, keep in mind that your system has no issues in most gaming scenarios.

If you are a marathon gamer, marathon anchor, or often let the GPU run for a long time (for rendering, mining, etc.), you may need to choose to guarantee the stability test. This is where Unigine's proof of payment auto-loop feature is most useful, especially when you decide to run this test while you sleep or go out.

If your system successfully passed this test, congratulations! You should be authorized ... well, almost anything. Running real games generally doesn't push your GPU as severely as the Unigine test, and 8 hours of overclocking under heavy use is considered very stable.

When testing the GPU pressure, you can perform a variety of tests. These tests are very useful if you have slightly outdated components and you want to make sure they still work as expected.

If you have recently overclocked the GPU, you will need to run a stress test to make sure it can run stably at a higher speed.

We recommend several different stress tests. Always remember that when running these tests, you need to pay close attention to the temperature of the GPU to ensure that it remains safe and stable.

One of the most popular GPU stress tests is Heaven & Valley Benchmarks. It is ideal for overclocking and general stability testing.

3DMark is another useful stress test. This tool can be used for many electronic devices, such as PCs and tablets. It measures pressure along with other things like temperature and clock speed.

The time to run the GPU stress test depends on the type of stress test you want to perform.

The longer the stress test, the broader the scope of the test. If you want to do a basic stress test to understand how

This is something you should do in rare cases, not on a regular basis.

conducts a 24-hour stress test to ensure that the GPU reaches the highest specifications. Letting the test run longer will help you better understand how the GPU is working and how it can cope with stress for a longer period of time.

When it comes to stress testing, FurMark is a tool that doesn't always get the best reputation. In view of this, many players choose to avoid it altogether as a preventive measure.

Although FurMark itself is not bad, but unlike other GPU pressure tools, it adds additional pressure to the GPU, which is not always necessary. Although some GPUs can handle this problem, others may not.

For this reason, FurMark can cause the graphics card to overheat, causing irreparable damage to the GPU. If you really want to use FurMark, it is a tool that you should only use for a short time, not a few hours.

No, sadly there is no way to test the GPU without using a PC. This is because the GPU needs power to work. Without power, the test cannot be performed.

If you want to know the benchmark or stress test results of a GPU and cannot run it on a PC, it is best to always check the manufacturer's website to see if they have test results. In addition, there are many websites that specifically test this.

When you compare your GPU with Heaven, it does not need to run for a long time. On average, players tend to run Heaven for about 12 hours. This will allow them to fully understand your GPU's ability to cope with pressure. No need to run it any longer.

If you want to run a short test, it will only take about 30 minutes to complete. However, long-term testing is not always necessary, and 15 minutes is usually sufficient to gather all the information you need. Chapter

That's It! We hope this article on GPU stress testing helps you answer any questions about stress tests and how they are run. If you are an overclocker, we look forward to helping you maximize your graphics card performance. If you are here to diagnose the system ... we hope you will pass the test (or solve the problem)!
